To all whom it may concern:

Be it known that I, WILLIAM H. BROADWAY, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful Im rovements in Machines for Ornamenting V ibod, of which the following is a specification.

The invention to be hereinafter described relates to machines for ornamen'tin wood and like surfaces, and more articu arlyto machines of this general t pew erein the natural surface of one kind 0 wood is reproduced in imitation u on another character of wood. Inthis genera form of machineit is essential that the roller, formed of suitable'compositi'on, shall be of such dimensions and character that the natural surface to be reproduced may be first transferred to the face of the roller and thereafter by movement of the wood to be ornamented beneath and in con tact with the roller, that such surface be transferred in perfect condition to the Wood under treatment. The practical efficiency of the machine, perfection of the re roduced surface, and economy of product wi I depend upon the relative disposition of the roller and its adjunctive devices, the accurac and readiness with which the roller may e adjusted to its Work, and the facility for cleanmg and drying the surface of the roller in 'pre aration for subsequent operations.

he object of the invention is to provide a machine of the character indicated which shall be simple in construction, efiicient and accurate in operation, and wherein means are provided for readily cleaning and drying the printing-roller and adjusting it to proper operative relatiorrto the wood to be ornamented; and the invention consists of the parts and combinations to be hereinafter described and then definitely pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a machine embodying the present invention; Fig. 2 is a transverse vertical section of the machine on the line2 2, Fig. 1, looking in the direction of the arrow. Flg. 3 is an enlarged detail showing some of the parts in section, illustrating the printingroller, its adjusting devices, and adjacent parts.

In the embodiment of the invention illus- Itrated, the machine is specially adapted for ithe reproduction or imitation on any desired character of wooden strips or slabs of such surface as is presented by quarter-sawed oakor analogous character of hard wood, although it is to be understood, of course, that the invention is not limited in this respect.

The main supporting-frame may be of any sutable construction, and, as shown, is formed of the lon itudinal side pieces A, supported by I uprights which in turn are united longitudma A respectively, Figs. 1 and 2. Between the side pieces A are the tracks A A, extending substantially the full length of the machineframe, and upon these the table B is su ported by means of rollers b b, so that sai table may be easily moved longtudinally upon said tracks. Extending from the bottom of the table B is a rack 12, Figs. 1 and 2, adapted to be engaged by and be operated by a pinion b (dotted lines, Fig. 2,) mounted ona shaft 6 to which motion may be applied by any suitable meansas, for instance, the hand-wheel b*whereby the table B maybe reciprocated longtudinally-of the supporting-frame, as will be obvious. It is to be understood, of course, that the invention is not confined to the particular means shown and described for reciprocating the table B, since any devices and driving mechanism may be employed for that pur ose, as will be fully understood'by one skiiled in the art.

- Disposed substantially midway in the length of the main frame, on each side thereof, are the roller-standards C 0, extending some distance above the top of the main frame and connected by the cross-pieces C, carrying the bearing-guides c c. T 's frame for identification may be termed the auxiliary frame.

The printin *roller D, which may be made of any suitable composition adapted to receive the impression, as hereinafter described, is carried by a shaft d, mounted in bearingblocks (1 d, Fig. 3, which are movable vertically between the bearing-guides c 0. Extending between the roller-standards C C be-.

= low the cross-pieces C C are the bracketarms E E, secured to the standards 0 C by suitable means, as the bolts 6 6, (see Fig- 3,) and preferably sup orting blocks E E, in which are rotatab y mounted adjustingshafts E E said shafts being also j ournaled near their opposite ends in the framing, as at E I Fixed to the bearing-blocks d d are the adjusting-screws F F, Fig. 3, extending downward through suitable bearings in the cr0s s pieces 0 and a guidinga erture in' the bracket-arms E, and screwt eaded on the ly and transversely by the ties A and adjusting-screws F F are the bevel-gears f.

whereby upon rotation of the bevel-gears f the adjusting-screws F may be raised or lowered to properly position the printing-roller, as will be understood. In order that the adjusting-screws F at each side of the machine may be moved simultaneously and in equal amounts, Iprovide the other ends of the adjusting-shafts E with bevel-gears g and connect them with correspondingly beveled gears 91 fixed to a cross-shaft g, extending between the adjusting-shafts As a means for operating the adjusting-shafts a hand-wheel g may be applied to one of them. Details of the adjusting mechanism for the impressionroller may be varied, of course, within the scope of the present invention, the essential in this respect being that the impression will be provided with adjusting devices simultaneously acting on each end of said roller under hand manipulation to adjust the roller evenly and accurately with relation to the surface to be treated.

7 Having described the frame, the table, printing-roller, and their coacting instrumentality, it will conduce to a more comprehensive understanding of the remaining features of the invention to refer to the general operations whereby the desired impression is transferred to the wood to be ornamented. Assume, for instance, that it be desired to give the appearance of quarter-sawed oak to pine or other character of board. The quarter-sawed oak board is first fixed upon the table and worked out with a wire brush to open the grain. It is then inked and scraped off with rubber scrapers. The table and board thus prepared are then moved under the printing-roller, which has been previously adjusted to receive from the prepared board the impression desired. The prepared board is now removed and the pine or other board to be ornamented is placed upon the table, or the board to be ornamented may be placed on top of the prepared board and the table and board then moved under the roller, whereby the desired ornamental surface is transferred, so that the treated board presents an accurate resemblance to that from Which the impression has been taken. In such operation it is obvious that the printingroller is liable to become dirty to an extent that will prevent an accurate reproduction of the'desired impression, and the importance of a ready means to clean and dry the rint ing-roller becomes obvious. This I wil now explain.

Disposed normally below the. printingroller and substantially midway in the length of the machine-frame is the fluid-tank H,

having guiding-pieces h h projecting downward therefrom, Fig. 2, said pieces engaging suitable guides, as h h, Fig. 1, on the main frame. The purpose of these pieces h h and the guides h h is to insure the proper vertical movement of the tank H, as will presently appear. Pivotally mounted on the main frame at h is the foot-lever or treadle H, the inner end h of which is connected to the tank H by means of the rods h, so that upon depressing the foot-lever at its outer end the tank will be raised to cross the path of movement of the table B to bring it in position close to the surface of the printing-roller D,

and by removing the foot from the said lever the tank will at once drop away from the printing-roller, as will be obvious. Since the table B is reciprocated back and forth beneath the roller, it is necessary that the fluidtank shall be normally below the path of movement of the table, and it is raised and lowered acrossthis path of movement to immerse the periphery of the roller in the fluidtank, which may contain benzene, by means of the treadle. When the fluid-tank is thus raised, it is necessary to turn the printingroller to subject all parts of its periphery to. the action of the fluid in the tank, and as one means of doing this I may provide a handcrank K; The cleansin action of the fluid, such as benzene or the like, in the tank thoroughly washes the surface of the roller and prepares it for the reception of another impression. Before giving it another impression, however, it is essential that the surface of the roller be thoroughly dried, to do which I provide a device which for identification may be termed a drier. This consists of a frame L, Fig. 3, extending transversely of the machine, as shown, and having a hinged connection I with the auxiliary frame or cross-pieces C, so that when 'cleanin the roller itmay be turned to have its e ge Z bear against the periphery of the roller; but when the device is being operated to receive or transfer an impression this drier may be turned away from the roller, as will be obvious.

Preferably I form the bearing edge leather, rubber cloth, or leather sponge or other absorbing material, so that the surface of the roller after being treated with the benzene or cleansing fluid in the tank is ther oughly dried. f

It will be obvious to one skilled in the art that many changes in details of the machine may be made within the scope of my invention and that the table may be reciprocated by power devices, if desired, and the raising and lowering of the roller may obviously be effected by power through the described mechanisms. 1

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
